Thanks for this very basic and yet so essential piece of "wrenching" advice.
I have NEVER thought to center the timing chain cover! No wonder mine
always leak around the seal!

As a general rule, the tightness of grade 5 bolts is based on it's size.
1/4"=6lb ft, 5/16"=14lb ft
The "Sump retaining bolts" call for 6 lb. ft. Any more than that, there
will be stretching of the oil pan lip and poor sealing. This will be the
same for the small bolts on the timing chain cover. Be sure to center that
piece before tightening any of those bolts.
The centering is easy. Start a few bolts in the timing cover less than
finger tight, then slip the crank pulley on and tighten a few bolts with
light torque. Take off the pulley and do the rest of the bolts.
